**  LONG RANGE OF SCANNERS
**
**	A summary of the quadrants that surround you is printed.  The
**	hundreds digit is the number of Klingons in the quadrant,
**	the tens digit is the number of starbases, and the units digit
**	is the number of stars.  If the printout is "///" it means
**	that that quadrant is rendered uninhabitable by a supernova.
**	It also updates the "scanned" field of the quadrants it scans,
**	for future use by the "chart" option of the computer.
